 # Issue #12: Implement Role-Based Access Control (RBAC) for Dispute Endpoints
 
 ## Description
-Implement role-based access control for dispute-related endpoints to ensure that only users with the appropriate roles can perform actions such as opening disputes, changing dispute status, and making final decisions.
+Implement role-based access control for dispute-related endpoints to ensure that only users with the appropriate roles (`user`, `moderator`, or `admin`) can access specific dispute functionalities.
 
 ## Acceptance Criteria
 - [x] Middleware `requireRole` is implemented and tested
-- [x] Dispute endpoints are protected by appropriate role checks
+- [x] Dispute endpoints are secured with appropriate role requirements
 - [x] Integration tests verify role-based access control
 - [x] Documentation of roles and permissions is updated

 ## Notes
-This issue builds upon the existing role-based access control implementation and focuses specifically on dispute-related functionality. The middleware should be used to protect endpoints in the dispute flow.
+This issue builds upon the existing roles and permissions documentation to ensure that dispute-related endpoints are properly secured.
